Ex Libris Anonymous creates these fun, functional and completely UNIQUE journals. Each one is one of a kind as they are all made from recycled book covers. The journals are filled with about 75 sheets of 24/60#, acid free, BLANK paper, which is a nice journaling or sketching paper. inside the front cover and throughout every book we retain any beautiful cover pages, illustrations, library cards, maps, inscriptions, or what-have-you found in the book (we find all kinds of beautiful stuff in these old books). and it's all held together with a black plastic spiral.
